IP QoS
UKLight
• e-science: huge end-to-end data flows
• Will this be possible with IP networks?
• UKLight project:
• End-to-end Gbps bandwidth
• Ultimate goal: application-controlled switching of WDM
wavelengths
• First steps:
electrical multiplexing
applications proof-of-concept
• Early adoptors
• Particle Physics - high performance data transfer
• Radio Astronomy - very long baseline interferometry
(near-real-time data transfer)
• Distributed HPC & visualization

JANET Developments
Challenges
SuperJANET5
Services – challenges
• Change in community.
• Increasing demand for services that we
have not previously provided (e.g.):
• web mail, filtering and hosting; and
• off-site resolver.
• Increasing emphasis on security services:
• security health check;
• central e-mail testing; and
• site incident investigation service.
Challenges…
• Connection of Adult Community Learning
community.
• Connection of schools.
Education networks
10 regional networks
144 local education
authority networks
Scottish Schools Digital Network
– built over SuperJANET in Scotland
– 32 local authority networks
Lifelong Learning Network Wales
– attached to SuperJANET in Cardiff
– 22 unitary authority networks
Challenges…
• Connection of Adult Community Learning
community.
• Connection of schools.
• Upgrade of FE community.
• Reliability
• Change in use of internet by HE and FE
• Critical to the business

From requirements to
solution
Reliability
• minimise single points of failure
• reduce components and complexity
Scalability
• UKERNA control of costs of adding large
amounts of bandwidth when needed
Separability
• configure parallel purpose-built networks via
control at transmission-level
Flexibility
• UKERNA ability quickly to change
configuration of network when needed
Key objective …

Components
• building block: raw bandwidth channels
• 2.5Gbps / 10Gbps or subdivisions (e.g. 1G
Ethernet / 155Mbps) – 40Gbps in the future
• IP production service built over channels
• other services also built over separate
channels
• e.g. high-capacity bandwidth channels:
– Regional Network/Regional Network or
– RNO/international (UKLight integration)
